Photographic astrometry (proper motions and accurate positions), photometry (in the photographic R and I passbands) and membership probabilities for high probability proper...

The Asiago photographic archive has been searched for plates containing the symbiotic stars Hen 2-468, QW Sge, LT Del, V407 Cyg, K 3-9, V335 Vul, FG Ser and Draco C-1. A total...

This catalog is the result of a program of photographic photometry. Four plates each were taken of M67 in U, B, and V, and were measured and reduced using the standards of...

Gaia Data Release 2. Summary of the contents and survey properties: We present the second Gaia data release, Gaia DR2, consisting of astrometry, photometry, radial velocities,...

(no description available) Cone search capability for table J/MNRAS/240/785/appendix (ubri photometry)

Photovisual and photographic magnitudes of more than 400 stars in the globular cluster M22 have been measured. The resulting color-magnitude diagram extends to slightly fainter...

The SPM4 Catalog contains absolute proper motions, celestial coordinates, and B,V photometry for 103,319,647 stars and galaxies between the south celestial pole and -20 degrees...

USNO-B1.0 (Cat. I/284) and 2MASS (Cat. II/246) are the most widely used full-sky surveys. However, 2MASS has no proper motions at all, and USNO-B1.0 published only relative, not...

The Naval Observatory Merged Astrometric Dataset (NOMAD) contains astrometric and photometric data for over 1 billion stars derived from the Hipparcos (I/239), Tycho-2 (I/259),...

The SPM Catalog 2.0 provides positions, absolute proper motions and photographic BV photometry for over 320,000 stars and galaxies. The Catalog covers an area of ~3700 square...

A photometric UBV survey is presented for 610 stars in a region surrounding the Cepheid AQ Puppis and centered southwest of the variable, based upon photoelectric measures for...

This version is a preliminary adaptation of the APM, covering the Northern sky at high galactic latitudes only. The catalogue APMCAT-POSS1-1.0 is derived from the first epoch...

USNO-A1.0 is a catalog of 488,006,860 sources whose positions can be used for astrometric references. These sources were detected by the Precision Measuring Machine (PMM) built...

Photographic BV photometry has been performed for stars in the southern globular cluster NGC 6139. Equatorial coordinates have been determined for the ten variables recognized...

Accurate equatorial coordinates have been determined for variable stars in the globular cluster NGC 3201. Results of photographic BV photometry are presented. Cone search...

This paper is partly a review of the history of the making of the Mount Wilson Catalogue of Photographic Magnitudes in Selected Areas 1-139 (hereafter the MWC), begun in 1909...

Time-series photographic photometry for the variable stars in M9. Cone search capability for table J/other/PDDO/1.511/stars (List of studied stars)

175 plates of the globular cluster M30 in Capricornus, taken mainly in the years 1946, 1947 and 1948, with the 24-inch reflector, have been the object of a photometric...

The distance modulus of M92 is determined from the bright stars and the mean magnitude of 12 cluster-type variables. From the former, m-M=14.93; and from the latter,...

New observations from the southern hemisphere have been used to check the periods for the 11 RR Lyrae variables in and around the globular cluster Messier 9. The periods were...
